seismic lithology

The foundation of forward modeling band together the geology modeling and seismic modeling organically, not only to distinguish the lithology, but also analysis hydrocarbon effectually.

正演模型的建立将地质模型和地震模型有机地结合起来，不仅能区分岩性，也能进行有效的烃类检测。

Based on core observing, 3700 logging and imaging log interpretation technology, terrestrial stress experimental analysis technology and seismic inversion technology, the paper investigates comprehensively the burial hill lithology and fracture distribution, and predicts the good fracture distribution zones.

利用岩心观察、3700测井及成像测井解释技术、地应力实验分析技术及地震储层反演技术等技术手段，对潜山储层岩性及裂缝分布规律进行系统研究，并对裂缝发育区进行预测。

Some changes in reservoir lithology and physical properties usually reflect in seismic wave form characteristics.

储层岩性、物性的变化往往表现为地震波形特征的差异,地震波形特征分析是岩性预测、油气预测的重要手段.

As poststack acoustic impedance inversion use the seismic data of full angle multiple stack, it weakens the reflection sensitivity of reservoir character. AVO analysis and inversion provides various lithology parameters, but it can be easily affected by many kinds of noise.

叠后波阻抗反演使用全角度叠加的地震资料，削弱了反映储层特征的敏感性；叠前AVO分析和反演能够提供丰富的岩性参数，但受噪音的影响较大。

Seismic Lithology Modeling Inversing results have higher distinguishing rate than other.

岩性反演剖面的分辨率更高，但成层性相对较差。

Based on lithology, lithofacies, seismic reflection, log response, paleobiology, tectonic cycle, contact relationship and isotopic dating, the lower paleogene in the Liaohe Basin is divided into 4 sequences and 12 subsequences.

根据岩性、岩相、地震反射、测井响应、古生物、构造旋回、接触关系及同位素年龄测定等，将辽河盆地下第三系划分为4个层序和12个亚层序。
